In 2001, ESS/CGECR researchers Ellen Druffel, John Southon and Susan Trumbore were awarded million by the W. Keck Foundation for the development of an accelerator mass spectrometry (AMS) facility – the Keck-Carbon Cycle AMS facility - for radiocarbon measurements in support of carbon cycle research at University of California, Irvine.
